An MR fingerprinting method using dual echo EPI was developed in this study for simultaneous quantification of T1, T2, T2*, proton density and off resonance. In vivo evaluations performed in patients with lower grade glioma tumor demonstrated the ability of the technique to acquire multiple reflexivity maps within a clinically manageable scan time with each slice using 16 seconds and achieving total brain coverage in approximately four minutes.
